Multiple subdomains with SSL under IIS

iis ssl https subdomain

I currently need to have 2 subdomains under the same domain under SSL.
Both subdomains (www and affiliate) are on the same IIS server, under the same IP, and each one has specified a host header value (www.mydomain.com and affiliate.mydomain.com)

The first subdomain (www), which is the default, works great, with and without SSL.
The second subdomain works perfect under HTTP.

The problem is that I just purchased and installed the SSL certificate for the affiliate subdomain, and when you go to https://affiliate.mydomain.com, you get redirected to http://www.mydomain.com

I'm guessing the problem lies in the fact that I can't specify a host header value for SSL? (the dialog where I normally set the host header value doesn't have that option in the bottom part, dedicated to SSL).

What can I do about this? Should I have each subdomain in a separate IP? Is this not doable at all?

Thanks! Daniel

"I'm guessing the problem lies in the fact that I can't specify a host header value for SSL"

You guessed right. You will need two IP addresses.
